Abstract:
The laboratory experiment was conducted during 2020-21 having 19 treatments with 4 replications planned with CRD design. Freshly harvested lamb’s quarters variety Bathua - Pusa Green seeds were exposed to various physico-chemical dormancy breaking methods. For physical methods seeds were exposed to a different treatments and duration. For chemical treatments soaking duration was 48 hrs. Results revealed that, soaking of lamb’s quarters seeds in ethrel @ 100 ppm (T19) showed significantly highest normal seedlings (84.00%), root length (3.25 cm), shoot length (3.90 cm), seedling dry weight (3.15 mg) and seedling vigour index I (600) followed by seeds soaking in thiourea @ 1 per cent (T17) recorded normal seedlings (79.00%), root length (3.09 cm), shoot length (3.86 cm), seedling dry weight (3.05 mg) and seedling vigour index I (549) and lowest was observed in control (T1). For duration of seed dormancy results showed that, lamb’s quarters variety “Bathua - Pusa Green” exists up to 80 to 85 days after harvest with germination of 68.25 to 75 per cent, respectively.
